Abstract
The problem of efficiently generating or representing line drawings from the point of view of storage and transmission requirements is considered. A proposed solution is the use of mathematical techniques to characterize the various line segments of the line drawing. Towards that end, the B-spline technique is described and a new recursive relationship which simplifies the computations is given. The quadratic B-spline is then considered in detail and shown to be particularly useful as the basis of a line drawing generation algorithm.
